Hah, I guess I lost track of this thread.
I have a pair of Bourke's, the OG coloring. My experience is pretty much the same as Lisa's - I think they're delightful birds and I consider myself lucky that they were the species I selected. Anyone who thinks they're boring simply isn't watching them. . . well, unless you're watching them when they're having a snoozle, in which case, yeah, not a thrill a minute. But, they don't nap as much as they used to and when they're awake they're fun to watch.
Where my experience differs is that my two almost certainly weren't hand-fed. Between that, the fact that there are two of them, so they don't really need me to have a social life, and that we had a step back when I moved them from living in a cage with carefully monitored out-of-cage time to an aviary that they're in full time, mine aren't hand-tame.
We're working on it - I say "we" because Mustrum is putting a great deal of effort into training me to bring in their seed dish on cue, and I'm teaching them that the clicker means "I just put something tasty in your treat cup." But if someone is looking for a bird that's people-friendly, and Bourke's otherwise meet their preferences, I'd say to make sure to get them from a breeder that socializes them early and, if possible, meet the bird in advance to see how friendly it is with you.
The things I would add about my birds is that they basically don't climb at all. Esmerelda, if she's trying to go from one perch to another one that's close but slightly higher will sometimes use a bar to give her a boost up, but it's not like she'll use the bars (their travel cage has horizontal bars) to actually climb any distance. If Mustrum needs to go from a point A -> B that's too far/high to hop will just push off from wherever he is and fly to where he's going.
Which goes to the other thing that's awesome about them - they're amazing flyers. Just getting around their aviary requires a fair amount of flying during the course of their day (although they do have a mono-rope system which they can also use to move around). But, aside from that, they'll take off and sprint fly around their enclosure for no reason that I can see, just an attack of the "gotta flys" I guess.
One of the particularly cool flying things they've been doing started recently. When they were flying for fun, they used to mostly fly back and forth or in an oval in one plane. Because of how their aviary is set up, a little above head height for me was the plane they were usually flying in. Of course, they regularly used their flying up and down skills to get to perches or their dinner table, but fun flying was usually at one level.
In the last couple of months, they've upped their game. Now (sometimes with a running start from the back) they'll launch themselves off their seagrass hammock, swoop down to within a couple of feet from the floor, and then pull up hard so they're back to around 5-6 feet, before wheeling around to hop on a perch and contemplate how talented they are. Since they accomplish that all in a length of around 5 feet, that's some powerful flapping to make that nearly vertical ascent. It's like a roller coaster for birds.
I don't know if this is common for Bourke's, but mine are adventurous eaters - if I give them something and present it as food they'll usually at least try it. Yes, even pellets.
Anyway, yes, awesome birds for someone who will appreciate them for who they are.
